chapter 3 states of matter

1. complete the table about states of matter.

state	shape	volume
liquid		not definite

kinetic theory (page 71)

1. define kinetic energy.

1. circle the letter of the phrase that describes all particles of matter in the kinetic theory of matter.

a. randomly arranged
b. constant temperature
c. in constant motion

explaining the behavior of gases (pages 72 - 73)

1. is the following sentence true or false? there are forces of attraction among the particles in all matter.
2. is the following sentence true or false? because of the constant motion of the particles in a gas, the gas has a definite shape and volume.

explaining the behavior of liquids (page 73)

1. do forces of attraction have a stronger effect on the behavior of the particles in a gas or in a liquid?
2. circle the letter of each factor that affects the behavior of liquids.

a. fixed location of particles
b. constant motion of particles
c. forces of attraction among particles

explaining the behavior of solids (page 74)

1. solids have a definite volume and shape because particles in a solid vibrate in ___ locations. circle the correct answer.

orderly several fixed

26 physical science reading and study workbook level b · chapter 3

Explanation:

1. Solids have a definite volume. Liquids have an indefinite shape.
2. Kinetic energy is the energy of motion.
3. In the kinetic theory of matter, all particles of matter are in constant motion, so the answer is c.
4. There are forces of attraction among the particles in all matter, so the statement is true.
5. Gases do not have a definite shape and volume due to the constant - motion of their particles, so the statement is false.
6. Forces of attraction have a stronger effect on the behavior of particles in a liquid than in a gas.
7. The constant motion of particles and forces of attraction among particles affect the behavior of liquids, so b and c.
8. Solids have a definite volume and shape because particles in a solid vibrate in fixed locations, so the answer is fixed.

Answer:

1. Solid - Definite volume; Liquid - Indefinite shape
2. The energy of motion
3. c. in constant motion
4. True
5. False
6. Liquid
7. b. constant motion of particles, c. forces of attraction among particles
8. fixed
